当手机预览方向更改为水平和绝对布局的额外边距时，XAML标题文本丢失

我有这个Xamarin XAML，它有一个带有标题文本的背景图像，底部有3个按钮覆盖。第二，如何删除3个按钮之间的额外边距

        <AbsoluteLayout>
        <Image Source="Flower.jfif" Aspect="AspectFill" AbsoluteLayout.LayoutBounds="0,0,1,1" AbsoluteLayout.LayoutFlags="All" />
        <AbsoluteLayout x:Name="ViewControls" AbsoluteLayout.LayoutBounds="1,0,1,0.1" AbsoluteLayout.LayoutFlags="All" Margin="0,20">
            <StackLayout BackgroundColor="Transparent" AbsoluteLayout.LayoutFlags="All" AbsoluteLayout.LayoutBounds="0,0,1,1">
                <Label Text="Relax" TextColor="White" FontSize="30" HorizontalOptions="Center" />
            </StackLayout>
        </AbsoluteLayout>
        <AbsoluteLayout x:Name="ViewControls" AbsoluteLayout.LayoutBounds="1,1,1,0.1" AbsoluteLayout.LayoutFlags="All" BackgroundColor="#66000000">
            <StackLayout Orientation="Horizontal" BackgroundColor="Transparent" AbsoluteLayout.LayoutFlags="All" AbsoluteLayout.LayoutBounds="0,0,1,1">
                <Button Text="Profile" BackgroundColor="Transparent" TextColor="White" HorizontalOptions="FillAndExpand" />
                <Button Text="Meditate" BackgroundColor="Transparent" TextColor="White" HorizontalOptions="FillAndExpand" />
                <Button Text="Theme" BackgroundColor="Transparent" TextColor="White" HorizontalOptions="FillAndExpand" />
            </StackLayout>
        </AbsoluteLayout>
    </AbsoluteLayout>

手机预览方向更改为时缺少XAML标题文本
水平的

这是由您设置的保证金（保证金=“0,20”）引起的：

<AbsoluteLayout x:Name="ViewControls" AbsoluteLayout.LayoutBounds="1,0,1,0.1" AbsoluteLayout.LayoutFlags="All" Margin="0,20">

以下是完整的代码：
